Probing Color Octet Electrons at the LHC
Résumé
Models with quark and lepton compositeness predict the existence of colored partners of the Standard Model leptons. In this paper we study the LHC phenomenology of a charged colored lepton partner, namely the color octet electron, $e_8$. We explore various production mechanisms of the $e_8$'s at the LHC. Assuming 100% branching ratio for the decay, $e_8\to eg$, we estimate the LHC discovery potential for the $e_8$'s. Our analysis shows that the LHC with 14 TeV center of mass energy and 100 fb$^{-1}$ (300 fb$^{-1}$) of integrated luminosity can probe $e_8$ mass up to 3 TeV (3.4 TeV) for the compositeness scale of 5 TeV.
